TOOL FOR APPLYING SHOE BUTTONS.

iApplication filed April30, 1926. Serial No. 1 l5,85 5.

This invention appertains to tools and more particularly to a noveldevice for applying buttons to shoes and the-like.

The primary object of the present'invention is to provide a buttonin'gtool embodying automatic means associated dlrectly with the tool forejecting the'button and leather from the' tool after the button has beenclinched in' placeby the tool.

H Another salient feature of tl18.111V Ilt10n1S the provision of anejecting arm plvotally mounted on one arm of the tool and movable intoand outof the path of the button by the operation of the sliding buttoncarrler.

A further object of the invention is the provision of novel means forh0lfllllg tll button in place and the fastener in place during theoperation'of the tool and noyel means forclinching the fastener, so asto insure the proper insertion of the shank ofthe fastener through theeye of the button without danger of displacing the button during theoperation of the'tool.

A still further object of the lHVBHtlOII 1S to providea novel toolof'the character described whichwillbe durable and etficie'nt in use,one that will be simple and easy, to manufacture and one which can beplaced upon the'market at a'reasonable cost.

With theseand-other objects in View, the invention consists inthenovelconstruction,

arrangement and formation of parts, as will be hereinafter morespecifically described, claimed,-and illustrated in the accompanyingdrawings, in which:

Figure 9 is a detail perspective View of the fastener employed for thebutton,

Figure 10 is apersp-ective view of the button and fastener after thefastener has been 15 having the forward end thereofprovided with asplitsleeve 16 for reciprocably receiving a plunger orpin'l'l' thepurpose of which will be hereinafter more fully described. The sleeve 16on each side of the split portionthereof isprovided with alined cars 18for the reception of a. screw 19 for adjusting the sleeve about theplunger or pin 17. The

rear end of the arm 15 is provided with a suitable manipulating handle20. Ata point inward ofthe sleeve 16, the arm 15 is provided with adepending leg 21 havingthe forwardly extending foot 22 which terminatesdirectly below and in vertical axial alinement with the sleeve 16. Asshown the .foot 22 is arranged in substantial parallel relation to thearm 16. The inner face of the foot 22 is provided with an integralattaching block 23, the forward end of which at its inner face isprovided with a recess or seat 24L- for the disk shaped base 25 of thefastener 26forthe button 27. The block 23 has associated therewith themeansfor holding the fastener 26in position during the application ofthe button to the shoe and this means consists of a U-shaped spring 2823. This forms an effective means for allowing spreading of the armswithout dislacement of the spring from off of the block or saddle. Theforward ends of the arms 29 of the spring 28 on each side of the seat orrecess 24 are provided with upstanding inwardly directed gripping ears32, which are adapted to engage the disk shaped base 25 of the fastener26 when the same is slid into the seat 24. It is to be noted at thispoint that the fastener 26 is provided with a pointed penetrating shank33 which is adapted to be clinched through the eyelet of the button.

The inner end of the plunger has the opposite sides thereof flattened asat 34 and the extreme inner end thereof is provided with an anvil 35which serves the function of clinching the shank 33 through the eyelet36 of the button 27. This anvil forms one of the features of theinvention and is provided with a straight inner guide face 38, whichgradually leads into the arcuate face 39 which forms the means forclinching the shank. The inner edge of the anvil is slightly beveled orrounded as at 40 for a purpose, which will be hereinafter more fullydescribed, while the outer face of the anvil is provided with a seat 41forthe reception of the eyelet 36 of the button 27.

In order to hold the button in position and the eyelet in alinement withthe arcuate face 39 of the anvil a holding spring 42 is provided. Thisspring 42 is of a U-shape in cross section and embraces the flattenedfaces 34 of the plunger. The extreme lower end of the spring 42 isprovided with inwardly directed spring fingers 43 for gripping theeyelet and holding the same in the seat 41. The forward front edges ofthe sides of the spring adjacent to the upper or inner end thereof isprovided with outturned resilient lugs 44 the purpose of which will alsobe hereinafter more fully described.

The spring 42 is held against displacement by means of a pin 45 whichextends transversely through the plunger and the sides of the spring 42.The terminals of the pin 45 extend beyond the opposite faces of theplunger and forms a bearing for the operating arm 46, as will now bedescribed. v

The operating arm 46 has its inner end bifurcated to provide a yoke 47which straddles the depending leg 21 and the yoke is pivotally connectedto the leg 21 ata point intermediate its ends by a suitable pivot pin48. The extreme forward end of the yoke 47 is notched as at 49 forresting on the terminals of the pin 45 and the bifurcated portion 47engages the resilient lugs or lips 44 of the spring 42 and these lugs orlips normally exert a tension thereon so as to prevent any lost motionbetween the operating arm and the plunger. The outer end of the arm 46is provided with a suitable manipulating handle 50.

An expansion spring 51 is coiled about the plunger 17 and is confinedbetween the sleeve 16 and a head 52 formed on the outer end of theplunger. This spring functions to normally hold the plunger and anvil ina raised position.

In connection with the plunger 17 I have provided a novel ejector 53which forms one of the main features of this invention. This ejector 53comprises an ejector arm 54 rockably mounted on a pivot pin 55 carriedby the arm 15 adjacent to the sleeve 16. The arm 15 at this point isslotted as at 56 to receive the ejector arm 54 and the upper end of theejector arm is provided with a cam head 57. This cam head is normally received within a longitudinally extending groove 58 formed in the plunger17 and the inner end of the groove is provided with an inclined face 59for engaging the head 57 and actuating the arm as will be laterdescribed. The lower or inner end of the ejector arm 54 is provided withan arcuate kicker foot 60 the purpose of which will also be hereinaftermore fully described.

It is to be noted however that when the plunger 17 is being movedinwardly that the inclined face 40 of the plunger will engage thearcuate foot 60 and move the foot out of the path of the plunger. I/Vhenthe plunger is in its extreme raised position the inclined wall 59 ofthe groove 58 formed in the plunger 17 will engage the cam head 57 IUUof the ejector and swing the ejector'on its pivot 55 for moving thekicker foot directly under the anvil or lower end of the plunger asclearly shown in Figure 5 of the drawings.

In operation of the improved tool the fastener 25 is grasped and thedisk shaped face 25 is slid into theseat 24 between the arms orresilientlegs 32 of the spring 28, after which the button is taken andthe eye let 36 thereof slid into the seat41 between the clamping jaws orarms 43 of the spring 4:2. The handles 20 and 50 arenow' grasped in theordinary manner and the plunger is placed over the leather where thebutton is to be applied. toward one another and the shank 33 of thefastener 26 will be forced through the leather and will engage first thestraight face 38 of the'anvil and then the arcuate face 39 of the anvil.This will clinchthe shank and coil the same back and through the eyelet36 of. the button. the shank is first bent before being passed throughthe eyelet 36 and when the shank The handles are now brought 3 It is tobe noted that fastener 26 and force the fastener, the but ton and theleather out of the-tool. Thus it is obviousfthat theapplication of thetool i's considerably facilitated by the inclusion of the ejector, whichas heretobe-e fore-stated forms one of the important featitreso'f 'theinvention.
